Metuchen, New JerseyWireless test equipment maker Berkeley Varitronics Systems (BVS) has a software update for its Yellowjacket 802.11b test receiver (we reported on the Yellowjacket when it first hit the market back in 2003).
The calibrated Yellowjacket receiver, based on a PDA, is used in sweeping and analyzing 2.4-GHz or 5-GHz so-called Wi-Fi RF networks. In use, the receiver measures all network channels for analysis of any access point's MAC (media access control), SSID (service set identifier), and RSSI (received signal strength indicator) signal levels.
The Yellowjacket can also run as an RF spectrum protocol analysis and direction finding tool. BVS's calibrated receiver sweeps and measures RF energy in the 2.4 GHz range as well as on each channel. It's accurate to within 1-dB.
The New Executables
BVS now has Yellowjacket v4.0 software for its Hewlett Packard iPAQ PocketPC-based platform. Best of all, the Web-downloadable update is a freebie!
The new Yellowjacket bits add several analysis screens, including an SNR screen (signal-to-noise ratio). New screens displayed on the iPAQ also include a channel frequency response screen, and an antenna alignment screen.
Additional features include a snapshot feature for all analysis screens, improved MAC (media access control) listing, and spectrum analysis screens.
